FINISHING MACHQNE FORTUFES AND THE LIKE.

Application filed January 17, 1919. Serial No. 271,578.

To all whom it may cmwem:

. Be-it known that I, MAGNUS NOTHEIS, a citizen of German and a residentof the town of North ergen, Hudson County,

6 State of New Jersey, have invented an Improvement in FinishingMachines for Tubesand the Like, of which the following is aspecification.

My invention relates to apparatus for finishing tubes and the like, moreparticularly collapsible tubes, such as are used for containing toothpaste and similar material of a plastic nature.- The object of myinvention is to provide apparatus of thegeneral character specified inwhich the'various desired operations are efficiently and rapidly carriedout,which apparatus shall be simple and economical in construction, andcertain in operation.

-By way of example, I have shown a preferred embodiment of my inventionin the accompanying drawings, wherein:

Figure 1 is a plan view of such embodiment; i i 25 Figure 2 is a sideelevation of the same; Fi ire 3 is a longitudinal cross-section of the cutch mechanism and associated parts Figure 4 is an elevational view ofone end of such embodiment; d

30 Figure 5 is a similar View, partly grammatic, of the other end ofsuch embodiment; I

Figures 6, 7, 8, and 9 are detail views, partly diagrammatic, of variousportions of 35 the device.

Referring to the illustrative embodiment here shown for purposes ofillustration only, the apparatus comprises ashaft 10, preferablyhollow,- carrying at one end thereof to a work-supporting spindle 11,and at the other end a threaded sleeve 12.

The shaft 10, which, as has been stated, is

preferably hollow, is provided at the spin-.

is internally tapered to co-operate with and osition the tapered end 17of the spin e 11.

[The threaded sleeve 12 is keyed to the other end of shaft 10, asindicated at 19. The usual washers 20 and oil port 21 are provided. At22 is also shown an adjustable collar for properly positioning arts 12and 20 on shaft 10. p

The shaft 10 rotates within a pair of bearing sleeves 23 and 24 whichare carried by the standards 25 and 26, res ectively. Also mounted onshaft. 10 is a c utch generally designated by. reference character 27,and

comprising a reciprocatable member 28, havmg the friction cones 29 and30 at opposite ends thereof, for engagement with the inner conicalfriction surfaces 31 and 32 of the pulleys 33 and Y34:, respectively.

The pulleys 33 and 34 ride loosely on shaft 10 and are driven inopposite direc-. tions by any suitable mechanism, such as belts," nothere shown. Member 28 is capable of suflicient reciprocating movementalong shaft 10 to enable it and cones 29 and 30 carried therebyalternately and at predetet mined times to engage the friction surfacesof either pulley 33 or pulley 34:. Provision for such reciprocatingmovement of member 28 is made by providing a collar 35 which is' seatedwithin the recess 36 of the member 28. I The collar 35 is attached tomember 28 and to shaft 10 so as to cause parts 28 and 35 to rotate withshaft 10, as by means of a pin 37, shaft 10 being slotted as indicatedat 38 to enable member 28 and pin 37 to shaft.

The spindle 11 which, as shown, is readil removable from shaft 10,consists, in a dition to the tapered portion 17 'alrea-dy'described, ofa cylindrical portion 39 and a conical or ta ered end portion 40 whichcarhave the necessary play along said ries a three ed rojection 41 for apurpose I subsequently to described.

The machine is preferably provided with aplurality of finishing tools,such as a.

wil

threading tool generally indicated by ref- Y erence character 42,atrimming tool generah ly indicated by reference character 43, and acutting tool generally indicated by reference charactere. The threadingtool42,

more clearly shown in Figure 5, comprises a thread-cuttin knife or"membenf45i-fwhich 1 is removably attached-as lay means" binding screwto, to an arm 47 carried by a sleeve 48, keyed, as by means of the key49, to a rocking shaft 50. The sleeve 48 also preferably carries asegmental toothed gear 51 for engagement with a pinion 52- rocking arm58. At its other end, the rod ficiently ion i V 12 carried by shaft 10.The threaded block frame. The roller 66 is pivoted to the area 50carries the sleeve 48, keyed thereto as already described. Pinion 52 ismade sufso that segmental gear 51 carried by sha t 50 may reciprocate asubstantial distance with respect to pinion 52 for a purposesubsequently to be set forth.

The cutting tool 44 comprises an arcuate arm 59 loosely pivoted to therocking countershaft 53 between collars 6O fixed on said countershaft.The arm 59 carries a knife or cutting member 51. In the lower orinoperative position ofcutting member at, arm 59 rests against shaft 50.ln the upper or operative position of the cutting member ell, saidmember 4A is raised manually by manipulating the handle on free end 62of member 4st so as 'to bring the knife 61 by a pivotal movement intooperative position.

Arm 58, which is attached to block 57,

which in turn is carried by shaft 50 so as to oscillate and reciprocatewith said shaft,

.carries at its outer end the threaded block 63 for engagement with thethreaded sleeve 63 is held by gravity and by means of the tension spring64: in inoperative or lower position, as shown in full lines in Figure4.

The block 63 is raised into operative posi tion by means of a cam 65carried by arm 58, which cam may be acted upon by the roller 66 carriedby the arm 6? pivoted as at 68 to any suitable portion of the machine 67as at 59. Arm 6? is preferably pedal operated. For this purpose the freeend of arm 87 is pivoted as at 70 to a link '21, the lower end of whichis pivoted as at '22 to a pedal 73, which is in turn pivoted at 'Z'eland Y5 to a rod Z6 suitably borne by the standards '3'? and 78.

The various positions which the pedal may assume are diagrammaticall rillustrated in Figure 8. The neutral position of the pedal is indicatedas being substantially horizontal, and corresponds to the inoperativeposition of the bloclr -63 with respect to sleeve 12,

incense and to the disengagement of the cones 29 and 30 from the pulleys33 and 34;; the oblique position, shown in dotted lines, corresponds tothe position in which threaded block 63 will engage threaded pulley 12,and in which shaft 10 will rotate in one direction; the oblique positionindicated in full lines corresponds to the position in which b1ock 63does not engage pulley l2, and in which the shaft 10 will rotate in theopposite direction.

The link 71 is provided with a perforated or slotted arm or extension 79through which passes the link 80, the normal or neutral relativeposition between said link and arm 79 being maintained 1) any suitablemeans, such as the nut 81 a justably positioned adjacent one end of linkand engagingithe slotted or perforated end of arm 79. ink

80 is pivotally connected, as at 82, to one arm of a bell crank lever83fpivoted at 84: to any suitable portion of the machine frame. Theother arm 85 ofithis lever is in the form of a fork-shaped or arcuatemember which engages member 35 within flanges 35 of the same. The spring86.,which may be adjusted by providing an adjustable abutment 87, tendsto raise one end of the arm 83 to thereby bring friction cone 30 intoengagement with the friction surface 32 of pulley 34. The cone 30 is,however, normally kept out of contact with friction surface 32 by meansofthe engagement of bolt 81 with arm 79 in the normal or neutralposition of the pedal 73, in which position neither friction cone is incontact with the friction surface of its corresponding pulley.

The arm 58, carrying the threadedmemher 63, is provided with aprojection 88' -which is designed and adapted to cooperate with aledge-like projection or abutment 89. This abutment isadjustablysupported in any suitable portion of the'machine frame, as in part 90.For this purpose the abutment 89 is carried by a bar or slug 91positioned in a slideway -92 in part Any suitable manipulating device 93is Provided in the free end of bar 91 to enable the bar 91 and itsassociated abutment 89 to be read ily handled. Bar 91 and abutment 89carried thereby may be retained in adjusted position by .means of theset screw 94 pass ing through part Q0 in slideway92 for engagement withbar fill. lf desired, as shown, the threaded sleeve may be provided withan oil-feeding receptacle 95, the bottom of the receptmle being slottedto admit wiclrs of felt or the lilre, indicated at 96.. which serve tosupply oil. to the threaded pulley l2.

llli

, neeaeae that the tube 100 may be firmly retained.

and held in place during the various operations to which it is subjectedin the machine.

The threads on projection 41 are rounded rather sharp, and are of steeppitch, so as not to injure the nipple of the tube in. any

The operator nowdepresses the forward end of pedal 73 so as to raiselink 71 and arm 79 carried thereby. Arm 79, as already stated, isslotted or apertured so as to permit free passage of link 80therethrough.

The first effect of this operation is to permit spring 86 to rock. arm85 so as to bring friction cone into frictional engaging contact withsurface 32 of pulley 34, thereby causing spindle 11 to be rotated.

The continued depression of the forward end of the pedal 73, and theconsequent elevation of link 71, act to raise arm 67 carrying the roller66 against gravity and against the tension of spring 64. Roller 66 isthus brought to bear against cam 65 which is attached to arm 58 carryingthe threaded block 63; This serves to bringthreaded block 63 into 0erative engagement with the mtating threa ed sleeve 12. At thesame time,the pivotal movement of arm 58 carryingthreaded block 63, by reason ofthe engagement of roller 66 with cam 65, rocks or oscillates shaftcarrying the threading tool 42 and the segmental gear 51. This lastoperation brings the threading cutter 45 of the thread ing tool 42 intooperative engagement with the work, and by the engagement of segmentalgear 51 with pinion 53 serves also and simultaneously to bring thetrimming cutter 56 of the trimming tool 43 into op-- erative engagementwith the work.

The engagement between threaded block 63 and threaded part 12 acts tomove said block, and the arm 58, member 57, rod 50, threading tool 42,and the segmental gear 51, outwardly away from end 25' of standard 25,against the action of a compression.

spring 50' which surrounds rod 50 and lextends between a collar 105,keyed or other wise fixed to said rod 50, and said part 25.

At this stage of the operation of the machine the threading-cutter 45engages and travels along the nipple 102, the nipple and its associatedtube being constantly rotated on the spindle 11 in the direction alreadyindicated for this part of the operation.- Nipple 102 is thus threaded.r The end trimming tool 43, which is, unlike the thread-- ing tool 42,longitudinally fixed in position with respect to spindle 11 and the work100 carried thereby, serves to trim the end closure cap 103 of the-tube100.

At the same time, the operator manually raises the cutting tool 44 tobring the knife 61 thereof into engagement with the uneven end of tube100 so as to even and cut the same off at a predetermined distance fromtheshoulder 101, as indicated at 104. The

finished tube will therefore be of predetermined and even lengththroughout.

The operator maintains the pedal with its forward end in depressedposition, as above indicated, until the projection 88 on arm 58'carrying the threaded block 63 rides over and rests upon the ledge orabutment 89, the degree of elevation of the block 63 resulting' from theoperation of the pedal in the manner set forth above being sufiicient tomaintain said block in raised osition with the lower face of member 88's 'ghtly above or substantially on a level with the upper face of member89. The width of the roller 66 is such, as made more clear hereinafter,as to cause it to maintain block 63 in raised or elevated position inengagement with the threaded sleeve 12 in which position member 88 isover and above or resting upon member 89, and is sufiiciently small topermit block 63 to fall or drop out of engagement with threaded sleeve12 after member 88'is no longer over or on member 89. The block 63 isthus maintained in operative engagement with the threaded sleeve 12,since said block will be kept. in elevated position as long as theprojection 88 rests upon and rides along the adjust-able abutment orledge 89. i

As the threaded block 63 and the parts associated therewith continue tomove outwardly, corresponding to the threading and trimming operationsdescribed above, a point in the operation of the machine Wlll be reachedwhen the projection 88 will move clear away from the ledge or abutment89,-

Arm 58, carrying the threaded block 63, will, under the action ofgravity and of the tension of spring 64, drop away from threaded sleeve12, the pedalfbeing now still slightly depressed sufliciently to keepthe spindle rotating, roller 66 being sufiiciently narrow to permit thisdownward movement of block 63 even if the pedal 73 is kept in depressedposition at this stage of operation.

V Arm 58, carrying block 63 and its associated parts, all carried andsupported by rod 50, will therefore be returned to the imtialpositionset forth above by the action of spring 50". The dropping of arm 58 toits lower or non-engaging position oscillates tools l2 and to theiroriginal inoperative 11 are capable of relative longitudinal movement,neither tool 43 nor tool ll is capable of such movement with respect tospindle 11 and the Work carried thereby.

In order to readily disengage the work from the spindle 11 and itsthreaded binding projection 41, the operator first releases the pressureon the forward end of pedal to bring spindle 11 to rest and thendepresses the rear end of pedal 7 3, to thereby depress link 71 and arm79 carried thereby. Arm 71, in its downward movement. by abuttingagainst nut 81, will depress link 80 to thereby rock or oscillate arms83 and 85 of the bell crank lever against the action of spring 86 tobring friction cone 29 into operative engagement with friction surface31 of pulley 33.- lhis action will serve to rotate.

spindle 11 and the work, such as the tube 100, carried thereby, in adirection reverse to its previous direction of rotation. This reversalof direction of rotationis due to-the opposite directions of rotation ofpulleys 33 an 34, as already set forth. This reversal 'nf direction ofrotation of spindle ll acts by the inertia. of tube 100 and by theengagement of the hand of the operator with said tubeto disengage thethreaded projection ll from the inner surface of the nipple 102, and thefinished tube may therefore be readily removed from spindle 11. Theoperator then releases pedal 73 which returns to its neutral 'orhorizontal position, with the spindle at rest, and the series ofoperations described above ma now be repeated.

It is of course to be understood that my invention is not to be limitedto the specific form thereof herein shown and described for purpose ofillustration only.
